Teach machines with powerful data labeling tools

Classification and segmentation with powerful image annotation tools: bounding boxes, polygon, point, line, brush, and superpixel.

Imagery from drones and satellites are often processed to form a mosaic of an area using techniques like photogrammetry. Use Labelbox to create bounding boxes and polygons directly on the tiled imagery (zoomable maps). Ideal for drone maps, satellite imagery and even medical data.

The quality of your data determines the quality of your product. Real-time, automatic visibility and control over your data pipeline, no matter how many teams or collaborators.

Keep your teams efficient with live metrics, wherever they are.

​Label data with your team, an external team, or both.

Whether you have an in-house team of experts or are using a managed workforce to label data, you can bring all of this in one place with flexible collaboration and management tools.

​Integrate with the best frameworks and formats

Interface directly into TensorFlow's native format (.TFrecords).

Export in other popular formats: JSON, CSV, Pascal VOC, and COCO.

Learning is continuous

Create models that keep up with the real world. Monitor, improve, and manage model predictions with Labelbox.

from graphqlclient import GraphQLClient
